It's a long story, a map I started building in 2017
But I'm on the verge of releasing my map in two versions: one MOM dependent and with your version of the MOM inspired tracks.
I don't need anything else that MOM has - so I'll wait patiently when you finish this project.
BTW, a separate package with dedicated pillars that can be changed using NS or BOB is a very good idea.

I also had thought about doing separate elevated tracks with each of the different MOM pillars. I decided that it might be easier in the end to work out the pillars as a pillar pack that can be placed with 3rd party mods.

albeit for me to say how to make your map, but I wouldn't have thought prebuilt maps would include metro.Is there any particular networks you are waiting on?

Nice, so I waiting with publishing my map (MOM is dependency for it) until you publish all planed MOM inspired network. I think is better to wait and make my map MOM- free, with your replacement net on it.

I prioritised the two-way tracks, but do have plans to release the dual and quad one-way tracks as well as the station tracks for each of the station types and elevations.

I still can't believe You undertook the extraction of the MOM tracks!
I appreciate Your patience and your time (I tried to do this, but after a few tests I gave up :P )
Do you plan to (make) double one-way tracks as well as all types of station tracks (T, G, E)?
